This can be replaced with a wildcard.
Also, other systems may report a different value, e.g.:
$ grep -r MACHINE_ARCH sys/powerpc/include/param.h
sys/powerpc/include/param.h:#ifndef MACHINE_ARCH
sys/powerpc/include/param.h:#define MACHINE_ARCH "powerpc64le"
sys/powerpc/include/param.h:#define MACHINE_ARCH "powerpc64"
sys/powerpc/include/param.h:#define MACHINE_ARCH "powerpcspe"
sys/powerpc/include/param.h:#define MACHINE_ARCH "powerpc"
sys/powerpc/include/param.h:#ifndef MACHINE_ARCH32
sys/powerpc/include/param.h:#define MACHINE_ARCH32 "powerpc"
As such, I pushed an updated version:
